I know the dauer has an excellent body design for racing, but wouldn't the fact that it has a roof pose a problem? The Mercedes and Porsches that flipped did so largely because there is lift over their roofs at speed simply because the arc of the top of the car is longer than the arc under the car. As good as those cars are, their areo isn't as good for downforce as that of an open cockpit LMP. Cars like the bentley are kind of an exception because the roof isn't any higher than that of an open top car... but it would still subtract from the ammount of downforce. So what is it that would make the Dauer an exception?
